What is the function of lemma?
In mathematics, informal logic and argument mapping, a lemma (plural lemmas or lemmata) is a generally minor, proven proposition which is used as a stepping stone to a larger result. For that reason, it is also known as a “helping theorem” or an “auxiliary theorem”.
What is Palea in botany?
Palea (botany), part of the flower structure in some plants.
What are glumes in plants?
In botany, a glume is a bract (leaf-like structure) below a spikelet in the inflorescence (flower cluster) of grasses (Poaceae) or the flowers of sedges (Cyperaceae). Glumes may be similar in form to the lemmas, the bracts at the base of each floret.
What is an example of a lemma?

What is stigma in flower?
Stigma: The part of the pistil where pollen germinates. Ovary: The enlarged basal portion of the pistil where ovules are produced.
What is a sterile lemma?
Sterile lemmas are produced between the fertile floret and the rudimentary glumes (4, 14, 26). The sterile lemma has not been genetically characterized and is often mistaken for a glume. The present study showed that the G1 gene is specifically involved in specification of the sterile lemma.
What is Spike and spikelet?
Spike of spikelet inflorescence is a charactersitic of Poaceae. Flowers of Poaceae are characteristically arranged in spikelets, each spikelet having one or more florets. The spikelets are further grouped into panicles or spikes.
What is a floret in grasses?
In the grass world, a floret is a tiny grass flower with no petals, just male and female parts covered by bracts. In a grass spikelet, the florets line up, one after another, with a pair of glumes at the base. Awns are very helpful in identifying a grass.
What is the rice flower called?
Flower Anatomy. The rice “flower” is called a SPIKELET. The floral organs are what’s inside the lemma and the palea.
Which is the world smallest flower?
Watermeal (Wolffia spp.) is a member of the duckweed family (Lemnaceae), a family that contains some of the simplest flowering plants.
